Abstract

original image

NHCs go nano: Ruthenium nanoparticles were formed from (cyclooctadiene)(cyclooctatriene)ruthenium(0) and stabilized by N-heterocyclic carbenes (NHCs). Solid-state NMR spectroscopy revealed both the coordination of the NHC ligands on the surface of the particles and their surface reactivity.
